Answer (simplified and mix number):
B. 5/16
C. 6/1 or 6
E. 7/12
F. 7/3 or 2 2/3
Answer:
1/3 & option 1
Step-by-step explanation:
24) you are given the angle of red, and a circle is 360 degrees in all so:
red/full circle = 120/360 = 1/3
8) option 1 = a^2 + b^2 = c^2
The answer above is mostly correct, HOWEVER The ellipse is a vertical ellipse and therefore uses the equation (x^2/b^2)+(y^2/a^2)=1
a=10/2=5
b=8/2=4
put it in the equation and it is (x^2/4^2)+(y^2/5^2)=1
Simplify and the answer is (x^2/16)+(y^2/25)=1
Answer:
5 1/3
Step-by-step explanation:
2/3 x 8 = 2 x 8 / 3 = 16 / 3 = 5 1/3
Answer:
![x+2](https://tex.z-dn.net/?f=x%2B2)
Step-by-step explanation:
For this division we can first use factoring of the numerator, then eliminate the common factors.
![\frac{x^{3} +2x^{2} +x+2}{x^{2}+1 }](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B3%7D%20%2B2x%5E%7B2%7D%20%2Bx%2B2%7D%7Bx%5E%7B2%7D%2B1%20%7D)
Factoring the numerator by the term grouping method
![\frac{x^{2} (x+2)+(x+2) }{x^{2} +1}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%20%28x%2B2%29%2B%28x%2B2%29%20%7D%7Bx%5E%7B2%7D%20%2B1%7D)
![\frac{(x^{2} +1)(x+2)}{x^{2} +1}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%5E%7B2%7D%20%2B1%29%28x%2B2%29%7D%7Bx%5E%7B2%7D%20%2B1%7D)
